This invention relates to lasting machines and is herein 'shown as applied to 'a machine constructed generally as disclosed in United States Letters Patent No. 2,337,558, granted on December 28, 1943, on an application of mine, someportions of the 'machine being more fully sl'rown and described in Letters Patent No. 2,324,509,

4granted on July 20, 1943, on. another application of mine. It isto V.be understood, however, that in various novel 'aspects lthe invention `is not limited to the illustrativedisclosure.

VThe machine shown in the above-mentioned Letters Patent No. 2,337,558 is a toe-lasting machine provided with a toe former movable heightwise of the last to conform the toe-end portion of a multi-ply upper to the vcontour of the last by a wiping action thereon, with means for trimming from the margin of the toe end of the upper while 'itxis fheld `so 'conformed all but the outer layer of the upper materials, Vand with toe wipers which are movable heightwise of the last with the toe former and are later operated to wipe the margin of the outer layer of the upper inwardly 'over an insole on the last into position to be secured to the insole` by cement..

The machine is-also provided with grippers which grip the margin of the severallayers of 'the upper at the end and the sides of the toe, respectively, and pull it outwardly over the wipers preparatory to the upper-trimming operation, the grippers releasing the upper 'in proper time relation to the operation of the trimming means. After the trimming operation the upper is 'released also bythe toe former, which is retracted lengthwise and heightwise of the last, and lthe n operations of pulling it andiof wiping it heightwise of the last are repeated, the -grippers acting this time only on the outer layerK of the upper materials. Cement is then applied to the toe end of the shoe and the wipers wipe the margin of the outer layer inwardly over the Ainsole as above described. The machine is an automatic machine in which the various instrumentalities are operated at the proper times by uidpressure means4 to which operating fluid, 'preferably oil, is supplied from a 'common source where the fluid is maintained under pressure.

An object of the present invention is t'o provide means for also lasting the shoe Aalong the sides of the forepart beyond its toe portion. For this purpose the machine herein shown includes side Wipers which wipe the margin of the upper inwardly over the insole from thetoe portion to the beginning of theshank portion, these Wi-pers being moved heightwise of the last with the toe former and the toe wipers when the toe end of the upper is iirst wiped heightwise of the last 'by the toe former, since they are carried by a support common also to the toe former and the toe wipers. After the trimming Yof the toe end of the upper, but prior to retractive movement of the above-mentioned support heightwise of the last preparatory to the second wiping action of the toe former on the upper, the side wipers are operated to wipe the upper inwardly over the insole, and they remain ,in engagement with the overwiped margin of the upper as the support is thus retracted While tipping relatively to the support to increase their pressure on portions of the margin of the upper adjacent to the edgev of the insole. While they 'are over the insole the side wipers receive movements lengthwise 'of the last with an ironing action on the margin of the upper coordinately with similar movements ofthe toe former between its rst and second wiping movements heightwise of the last. After the second wiping Vmovement of the toe former heightwise of the last the side wipers are withdrawn from vover the insole in time to clear the toe wipers which are moved far enough lengthwise of the last to overlap portions of the margin of, the, upper previously engaged by the Side wipers. For operating thevside wipers the construction shown comprises cylinder-and-piston devices carried bythe above-mentioned support.

The machine herein shown also includes members arranged to clamp the margin of the upper against the edges 'of the side wipers and having the functions of what are commonly known as retarders as these wipers begin their Vwiping action on the upper, thus insuring that the upper will be tightlycpnformedhto the last and the insole. The invention further provides novel means for `controlling these retarders, the construction shown comprising meansvfor imparting to them positioning movements both heightwise of the last into engagement with the insole and outwardly over the insole toward the edge thereof in response to the n'iovement` of the above-mentioned wiper `support heightwise of the last prior to thegwiping operations of the side wipers. lAs the side wipers are movejd inwardly over the insole the retarders are moved heightwisejof the last 'away from the insole by pressure of the margin of the upper thereon, and devices `also controlled by movement of the wiper support heightwise of the last are provided for holding the retarders against return movements toward the in'sole when the side wiprs are withdrawn from over the insole, thus avoiding any interference between the retarders and the toe wipers in the movements of the latter over portions of the margin of the upper previously wiped in by the side wipers,

The above and other features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described with reference to the accompanying drawings and thereafter pointed out in the claims.

In View of the disclosures in the previously mentioned Letters Patent and in others hereinafter mentioned, only as much of the earlier construction of the machine herein shown as it is necessary to refer to for an understanding of the present invention will be herein described. For positioning the shoe there is provided a shoe rest member 2 which engages the bottom of the forepart of the insole when the shoe is presented to the machine by the operator, this member having thereon a spur 4 arranged to enter an indentation previously formed in the insole in predetermined relation to the edge of the shoe bottom, as more particularly disclosed in Letters Patent No. 2,391,461, granted on December 25, 1945, on an application of mine. The side gages therein shown for further positioning the toe end of the shoe laterally are, however, omitted. The

member 2 is supported on a casting 6 vertically adjustable along guideways on the frame 8. Substantially at the beginning of the cycle of power 5 operations of the machine the shoe is clamped against the member 2 by upward movements of a toe rest lll and an instep sup-port l2, as illustrated in Fig. '7, and near the beginning of the cycle also a heel rest I3 (Fig. 1) is moved into supporting engagement with the heel-end face of the shoe. These parts and others hereinafter described are operated by fluid-pressure means to which operating fluid is admitted at the proper times by valves controlled by a rotatabledrum (not shown), as disclosed in Letters Patent No. 2,337,558, this drum making one complete rotation in each cycle of operations.

For applying a pull to the toe-end portion of the upper the machineis provided with a toe-end gripper I4 arranged to grip the margin of the upper about the end of the toe' and with two side grippers I6 arrangedto grip it at the sides of the toe (Fig. 19). is positioned outspread between the open jaws of these grippers when the shoe is presented to the machine and they are closed on the upper by huid-pressure means in response to depression of a treadle (not shown) prior to the starting of the cycle of operations. Shortly after the beginning of the cycle the toe-end gripper is moved lengthwise of the last and the side grippers widthwise of the last to pull the upper, the grippers also receiving short upper-pullingmovements heightwise of the last. While the grippers are holding the upper under tension a toe former I8 which embraces the toe-end portion of the shoe is moved upwardly to wipe the upper heightwise of the last. Associated with this toe former are toe-embracing wipers 20 which later wipe the margin of the toe end of the upper inwardly over the insole. The toe former and the wipers are carried upwardly byV what may be termed a toe head 22 (Fig. 2) supported on two pairs of parallel links, the upper link of each pair being shown at 24. For moving thetoe head upwardly there are provided two fluid-operated pistons 26 (Fig. 1) mounted in cylinders 28, its upward movement being limited by engagement of lugs 30 thereon with screws 32 mounted on the frame of the machine. When the fluid is released from the cylinders 28 the toe head is moved downward by gravity. f Y n The toe wipers 26 are secured on the tops of two wiper holders 34 (Fig. 2) which are guided by a wiper carrier 36 for swinging movements Yabout an axis extending heightwise of the shoe to close the wipers inward laterally of the shoe, and the wiper carrier 36 is supported by the toe head 22 to move relatively to the toe head in directions 60 lengthwise of the shoe. Such movements vof the wiper carrier are effected by a fluid-operated piston 38 movable in a cylinder 43 fast on the toe 'f head 22, the piston being connected to the wiper c-arrier by a piston rod 42. WhenY operating iluid .65 is admitted to the rear end of the cylinder 40 the wiper carrier 36 and the wipers 20 are advanced bodily lengthwise of the shoe, and by means not herein shown in detail the wiper holders 34 are operated to close the wipers inward laterally of the shoe in response to this movement of the carrier. When the uid is admitted to the front end of the cylinder the wipers are retracted and opened.. The toe former I8 is movably supported on vthe Wiper -holders 34, as fully disclosed in Letters Patent N o. 2,337,558, and is controlled by two The margin of the upperV 'iearwar'cily -extending links sMl 'the rear -ends -of which are connected tothe lower ends of two Jdownwardly extendingforked arms ri formed-integralwitha sleeve d8 lfast'on a rockshaft 5@ #mounted in bearings in the toe'head 2'2. Another fdownwardly'extending larm 52 integral with the "sleeve'd is connected at its" lower Aend to a spring llwhichtends toturn the sleeve in the direction *to'impart forward movement to Vthe toe former. l"Ifo limit 'such-movement of the toe former there *istintegral with'the sleeve d8 anv arm 5t provided Withascrew arranged to engage a lug -6ll on "thetoe'head 22. By adjustment of this screw tlfe toe former is positioned in the proper relation tothe toe head for Vthe wiping of the upper heightwise of the last. The normal position of Ltlfie'wiper 'carrier '36 lengthwise of the shoe, when th'erei'snopressure in the cylinder 59, is deter- `rriined-,by two 'springs 52 Aand 64 mounted -in a cylinder "E6 which-is supported on the toe head, thesprings vbeing arranged to act on the wiper 'carrier vthrough means fully described in Letters TateritNofZB'S. By pressure of the fluid in th'efront end of the cylinder di) the wiper carrier 'isretractedbeyond its normal position against the vresistance ofthe spring fifi, the limit of its retractive'movement being determined by engagement of a collar 6B on the piston rod i2 with a shoulderi'lil on thetoe 'head 22. When the wiper jv:':a1`"rier is thus lretracted beyond its normal positionia'screw '1'2"thereon serves byV engagement with ,'one'ofthearms -45 also to retract the toe former LHi Ubeyondits normal position against the resistanoe ,of the'spring 54. As explained in the lastmentione'dhetters Patent, in operating on shoes r 'of *certain* styles the toe former may, if desired, "be heldin its fully retracted position during the greaterportion of t'ne next upward movement of the'ftoefhead 22 by engagement of a latch "ld with "the urear end of the arm 55 and then released by the latch to permit it to assume its normal position'determined by engagement of the screw 58 -with 'the'lug 60. To simplify the present description, howeverjit will be usually hereinafter as- 'sumed'that the latch 'ld isinoperative and accordingly that the toe former returns to its normal ,position-when the wiper carrier @E is returned by ther-spring lid-upon release of the fluid from the cfront end ofthecylinder 40.

'After the wiping of the toe end of the upper Vheightwiseof the last and while it is held conformed to the last by the toe former i8 its margin, otspread on the wipers, is operated upon by 4u,pperetrimming means to remo-ve therefrom all `butlthe-outer layer'of the upper materials, and laterin the cycle cement is applied to the toe end ofithe shoe by cement-applying means for secur- 'ingthe margin of the outer layer of the upper tothe'insole when it is wiped inwardly by the toe wipers. `As disclosed especially in Letters Patent No.'2,324,509, the upper-trimming means and the 'cement-applying means are combined for swing- L'ingrmovement as a unit about a vertical axis to bring-the cement-applying means into position over 4the shoe after the trimming means has operated thereon and for vertical movement to ybring each `of said means into operative position. '-I-heltrimming means comprises an end trimming knife`1$-movable lengthwise of the shoe (Figs. 8 and -1'9) anda pair of side trimming knives 18 movable wdthwise of the shoe. In operating on ithe' upper the cutting edges of the several knives nieve Iinl-aiplane-parallel to the top faces of the toeiwiperslZ atl a distance from these faces subs'ta-ntially'equal tothe thickness'of the outer-layer of the upper materials, the side Vknives acting on Lil.

The cement-applying means includes an'insole-engaging member-i8@ (Figs. 11

`and 20) "having therein a plurality of holes 8'2 'through which cement is forced as-the member in its 'downward movement approaches the insole.

'Formed on this member is an inclined face 84 (Fig. l2) by enga-gement with which'the margin vof the upper Vforces the member yiel'dinglyvupward-'away from the insole as the wipers v*20 lare moved inwardly, the-member accordingly having the function of a retarder.

At this pointthe manner of operation'of the machine `in lasting lthe toe-end portion of the shoe, which is substantially the same as described in Letters Patent No. 2,337,558, may be conveniently summarized with reference-to Ythe chart (Fig. '21) which illustrates-the timing of the different operations. vOn this chart ythe double lines indicate the times-when the loperating fluid is being admitted to the respectivecylinders -or is being maintained under pressure therein, van'cl the single lines indicate the times when the fluid is being or has been exhausted from thelrespective cylinders.

As previously explained, after the shoe has been presented by the operator in the position determined by the member 2 and its spur-4, the grippers I4 and l5 are closed byfluid-pressure means on the margin of the toeend of the upper pri-orto the starting of the cycler-of operations,

-thus enabling the ropera-tor to ascertainthat the upper has been properly gripped. Immediately after the starting of the cycle the toerest l and the instep supportlZ yare moved into engagement with the shoe as shown in Fig. 17 and the heel rest I3 also Vreceives its operative movement. Substantially at the beginning ofthe cycle,'mor.e over, uid is 'admitted to the front gend of the cylinder 40, as indicated at the 'bottom of the chart, to retract -the wiper carrier'36 from its normal position to the position determined by engagement .of the washer B8 .with the shoulder 1E), the purpose being to insure that the toe former, if the latch T4 is in use, will .be held in its `fully retracted position. Shortly thereafter the fluid is released from the front end of the cylinder, whereup-on the wiper carrier and, if the latch is not in use', the toe'former return to their normal positions. VNear the beginning of thecycle also the grippers Ill `and I`6 are operated to -pull .the upper in outward directions. While the grippers are holding the upper under tension `the upper-trimming and cement-applying unit is moved downwardly to bring the upper-trimming means into position to voperate on'the shoe and @upward movement is imparted to the .toe head `2.2 -tocausethe toe former lI8 to wipethe upper heightwise vof the last, the parts being then posi- `tioned as shown in Fig. 8. The next operation rperformed is .the trimming `of the nupper bythe fmovements of the knives 'I6 and `13, the action of I.the end knife "lr6 on the upper being villustrated inFig. -9. In the course of the'trimming opera- .'stion thefgrippers are opened rand are retracted to clear the knives. After the upper-trimming operation the trimming means is moved upwardly away from the shoe :and the knives receive their return movements.

Shortly after the trimming yof the upper fluid is again admitted to the front end of the cylinder 40 to retract the wiper carrier 36 to the position determined by engagement of the ycollar 68 `with the shoulder l and thereby also to retract :the toe former from the shoe lengthwise thereof, and while the toe former is thus held out of engagement with the upper the fluid is released from the cylinders 29 -to cause the `t-oe head 22 to carry the toe former downwardly, :as illustrated in Fig. 10. Just after the toe head starts to move downwardly the grippers are moved inwardly toward the shoe into positions where the outturned margin of the outer layer of the upper is between the grip-per jaws, as also illustrated in Fig. 10. At substantially the same time the upper-trimming and cement-applying unit is swung to bring the cement-applying means to a position over the toe end of the shoe. Thereafter the grippers are again closed and are operated to pull the upper as before, the pull being applied, however, only to the outer layer of the upper materials. The cement-applying means is then moved downwardly to bring the member 80 into enga/gement with the insole and to apply cement to the insole. At substantially the same time the fluid is released from the front end of the cylinder -40 .to f

cause the toe former again to assume its normal position lengthwise of the shoe, and the toe head is then moved upwardly once more t-o cause the toe former to wipe the upper heightwise of the last, as illustrated in Fig. 11. 'I'he toe wipers 20 are next advanced and closed to wipe the margin of the outer layer of the upper inwardly over the insole, t-he grippers being opened to release the upper just as the wipers begin to wipe it inwardly. In this operation of the wipers the member 80 is forced upwardly 'by the pressure of the upper on its inclined face 84, this member accordingly acting as la retarder on the upper and applying some oi the vcement to the inner face of the upper (Fig. 12). their inward movements are in positions such as illustrated in Fig. 13. After the wipers -have 4arrived in those positions iluid is released from the cylinders 28 to cause the wipers to increase their downward pressure on the margin of the upper. Thereafter the machine comes to a stop to -allow more time for the setting of the cement. After a brief interval it is again started to complete .the cycle of operations. During the remainder of the cycle the 4parts not valready in itheir starting positions are returned to those positions and the shoe is released. Before the wipers are retracted, however, from over the shoe fluid is -admitted again to the cylinders 28 to relieve the downward pressure of the wipers on the margin of the upper.

For purposes of this invention the opposite side portions of the toe wiper carrier 36 are extended forwardly toward the front of the machine, and secured by Screws 86 to these forwardly eX- tending portions are two castings 88 (Figs. 1, 2 and 4). Mounted in a guideway 90 in each of these castings is a slide 92 confined in the guideway by a cov-er 94 fast on the casting. Pivotally mounted o-n a pin 96 in the outer end of each slide 92 is a side wiper carrier 98 on the inner end of which a side wiper |00 is secured by screws 02. The side wipers |00 are constructed and arranged to wipe the margin of the upper inwardly over the insole along the sides of the forepart The Iwipers at the end of from the toe portion to the beginning of. the shank portion of the shoe in response to inward movements of the slides 92the guideways 90 for these slides being so arranged that the wipers in their inward movements widthwise of shoe.V have components of movement also lengthwise Y wardly to conform better to the curved contour of the bottom of the shoe heelwardly of the ball line.

Wiper-operating movements are impartedto the slides 92 by Huid-operated pistons I2 movable heightwise of the shoe in cylinders.V H4 which ar-e parts of the castings 88. Each Vpiston has thereon rack teeth H6 in vengagement with a pinion H8 rotatably mountedon a rod |20 in the casting 88, and integral with this piniongis another pinion |22 in engagement with rack teeth |24 on the slid-e 92. Each piston I2 is movable upwardly against the resistance of a spring |26 the lower portion of which is mounted in a. bore 'in the piston and the upper end of which is engaged by a plug |28 threaded in an upwardly extending cylindrical portion |30 of the cover 94. A rod |32 extending downwardly from the plug |28 assists in maintaining the spring in proper position. Wiper-operating movementof each slide 92 is limit-ed by engagement of a screw |34 carried by the slide with a stop face |36 (Fig. 6) on the casting 88. It will be understood that when the operating fluid is released from the cylinders |I4 the pistons ||2 and the side wipersy |00 are returned to their starting positions by the springs |26, their return movements being limited by engagement of portions of the Wiper carriers 98 with edge faces |38 on the castings 88, as illustrated in Fig. 4. Fluid is conducted to the cylinders |l4 from the source of supply through a conduit including a exible tube (Fig. 1.) Admission of the uid to the cylinders and release of the fluid therefrom at the proper times in the cycle of operations are automatically controlled by a valve (not shown) llike the valves associated with other operating instrumentalities of the machine in accordance with the disclosure of Letters Patent No. 2,337,558.

The pivotal mounting of the side wiper carriers 98 on the pins 96 permits relative movement of the side wipers |00 and the castings 88 heightwise of the shoe, as more particularly hereinafter explained. The normal position of each side wiper heightwise of the shoe relatively to the slide 92 is adjustably determined by a screw |42 which is threaded in the wiper carrier 9B and engages the top face of the slide 92, thecover 94 being provided with a slot |44 through which the screw extends. Threaded in the slide 92 is another screw |46 extending ythrough the slot |44 and through a spring |48 confined between the head of the screw and a socket in the wiper carrier 98. This spring accordingly holds the wiper carrier down in the position determined by the screw |42 but is yieldable to permit .the abovementioned relative movement of the Wiper |00 and the casting 88. Y -l Arranged to cooperate with each of the side wipers |00 in controlling the margin ofthe upper as itis wiped inwardly over the insole is a retarder which presses the margin of they upper against affairs@ the edge of the, wiper along the: widest. portion, of the forepart of the shoe and isy curved lengthwise of. the shoe: in. general, accordance with the curvature of the: corresponding portion` of the edge: ot the shoeA bottom..

Inl te prevent any interference betweenf the re .rdersand the toe wipers, the retarders: are'v held upraised in the positions tovwhich they; are' forced by the side wipers when the latter are, hdrawn from over the shoe bottom. For'this 'i pose 'there'is associated with an upwardlyI ex.- tending arm 'i32- of each of the levers |186 ai. latch Gfl pirotally mounted on aY pinf 206 on the: bracketi., and a spring 28 extending from the latch to the lever |86'. tends to swing the latch. downwardly. initially the latch' is held at such a; height as to clearthearm 20,2, asshown in;Fig;.14.f.. For this purpose a tail. 21o on thek latch' carries'. pin l' which extendsA through a slot 211|r in a link pivotally connected tothe arm |566? of the bell-crank lever |62, the, link inii'i'ally engaging' the pin at. the upper endl of ther slot.` When the toe head is first moved4 upwardly the upward movement of the' link 2|16` per-mits-l the`l latch to be swung. downwardly by the spring 208'-, the arm M32 being swung. simultaneously tosuchposition thatl the latch engages the end face of the arm as shown in Fig. 1'5. When the re- I tarder i5@ is.. forced-1 upwardly by the wiper |'0'0' the: arm 262 isswung reversely to sucl'i a positionthat the lat'oh is` moved by the spring 2118" into4 position to hold the arm, as shown'. in Fig. 16E The latch remains in operative position when the toe head: is thereafter lowered, since the-toe head at this` time, as hereinafter more fully eX'- plained, does not move all the way down because the wipers lili?. are positioned over the shoe. That is,V the' link .file does not move downwardlyw far enoughI to lift the latch. When the toe headlater receives its nal downward movement to starting position the latch is returned to its inoperative position.

The manner of operation of the side wipers and the retardersand' the timing oftheir move'- ments inthe cycle of operations-of4 the machine as a whole, while explained for the most part above. will now be briey summarized. It will beunderstood that when the shoe comes tothe machine it has already been subjected.v tothe usual pulling-over operation', the upper being heldlat the sidesof the toe near the location of the tip line by pulling-over tacks t' (Fig. 19), and" usually also the shank portion of the shoe has been lasted. Contrary, however, to the practice preferably involved in the use of thevmachines shown. in the previously mentioned LettersPatent, the shoe has not been lasted from. the toe portion to the beginning of-theshank portion, i. e., mainly at theball portion. Before the shoe is presented to the machine suitable lasting cement; which may be rubber latex, is applied to the margin or the insoleand the margin of the upper materials from the toe portion to theshank portionl When the toe head 2.2is-movedupwardlyfthe 11 first time to cause the toe former I8 to wipe the toe-end portion of the upper heightwise of the last, it carries the side wipers |053 and their operating mechanisms with it. By this upward movement of the toe head the bell-crank levers |62 are operated to move the retarders I Sil from the positions in which they are shown in Fig. 14 outwardly to the edge of the insole (Figs. 15 and 19) to spread the margin of the upper from over the insole, the retarders being at the same time moved downwardly upon the insole and pressed thereon by the springs |96. While the toe head is at the limit of its upward movement the trimming of the margin of the toe end of the upper takes place as already explained and, as indicated on the chart (Fig. 21), the side wipers are then operated to wipe the margin of the upper along the sides of the iorepart of the shoe from the toe portion to the shank portion inwardly over the insole into lasted position. As the side wipers are thus moved inwardly they force the retarders upwardly away from the insole to positions where they are retained by the latches 2M. While the side wipers are over the shoe bottom the toe wiper carrier 36 receives its short retractive movement lengthwise of the shoe to disengage the toe former l 8 from the upper, and as a result of that movement the side wipers supported by this oarrier have an ironing action Aon the margin of the upper lengthwise of the shoe toward the end of the toe, their flexible plates |36 also pressing more rmlyon the insole the `portions of the margin of the upper opposite the downwardly curved portions of the last bottom extending heelwardly ofthe ball line. The toe head is then moved downwardly, as hereinbefore described and as illustrated in Fig. 10, to retract the toe former heightwise of the shoe preparatory to its second upwiping'action on the upper. Since the side wipers are still over the shoe at this time the toe head does not move all the way down to its initial position, its downward movement being limited by the engagement of anges 2 i8 on the side wiper carriers 98 with stop faces 220 on the slides 92 (see Figl 17). It will be evident that in response to the downward movement of the toe head the side wipers receive tipping movements against the resistance of the springs |48 about axes extending lengthwise of the shoe, i. e., about the pins 95, thus increasing their pressure on portions of the margin of the upper near the edge of the insole (Fig. V16). When the toe wiper carrier 36 is thereafter moved forwardly to cause the toe former to assume the proper relation to the shoe for its second upwiping action on the upper, the side wipers have a second ironing action on the margin of the upper, this time in a heelward direction. After the second upward movement of the toe head, in the course of which the side wipers return to their normal positions in relation to the slides 92, the side wipers are retracted from over the shoe bottom in time to clear the toe wipers which in their o-perative -movements overlap to some extent lengthwise of the shoe portions of the margin of the upper previ- -ously wiped inwardly by the side wipers (see Fig. 18). When the side wipers are thus retracted the retarders |50 are still held up by the latches 291i to prevent interference with the toe wipers, the latches thereafter being moved to inoperative positions in response to the nal downward movement of the toe head during which the retarder-controlling levers |52 are returned to their initial positions.
